i was in a park in brooklyn, i noticed that the sky looked like it was moving becuz the clouds were being blown by the wind. from behind the clouds i noticed a white glowing sort of teardrop shaped craft, behind it, tailin it was a little blue dot. It seemed to be attached or being pulled by a blue glowing beem.

It was moving pretty fast , but it seemed to circle the whole park which is at least 4miles in diameter. then it just left it made no sound at all.....
